A de-Sitter no-hair theorem for spacetimes with isometry group forming two-dimensional orbits.

Abstract:

I present how some numerical and analytical general relativity techniques allow us to show how inflation, or a local region of de Sitter space, gets started notwithstanding very inhomogeneous initial conditions and the potential formation of localized singularities.
